IMPROVEMENT IN STOVEFPIPE SHEL-VES.

Specification forming part of Letters Patent No. 125,541, dated April 9, 1872.

Toall whom it may concern:

Be it known that I, HENRY P.y CHAPMAN, of Centre Brook, in the county of Middlesex and State of Connecticut, have invented anew Improvement in Stove-Pipe Shelf; and I do hereby declare the following, when taken in connection with the accompanying drawing andthe letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents in- Figure 1, a top view; Fig. 2, a side view; Fig. 3 a central section on line rv rc, and in Fig. 4 a central section on line y y.

This invention relates to a device for attaching a shelf to a stove-pipe, and consists in a clamping-ring, in two parts, to surround the pipe and be secured, thereto, and having an annular groove into which the inner edge of the shelf is placed, a flange beneath extending out to support the shelf, and so as toV a1- low the shelf' to be turned around the pipe, the said annular groove forming the bearing for such turning, as more fully hereinafter described.

A is the stove-pipe 5 B, a ring formed in two` said flange is chambered out upon the upper side, as at fn. (See Figs. 3 and 4.)` D is the thus formed and set into the groove is supported by the flange C beneath, and may be turned around the pipe, as denoted in broken lines, Fig. 1, the said groove d governing the position and movement of the plate, so that wherever placed it bears Vthe same rela` tive position tothe pipe.

To prevent the shelf from being displaced I make a projection, b, upon the under side, as seen in Fig. 4, to set into the recess n in the upper side of the ange C, so that the plate cannot be accidentally drawn from its place except when turned,`so that the said projection b corresponds to the opening j' through the flange, in which position the shelf may be removed or replaced.

I claim as my invention- The ring B, constructed so as to be clamped around the pipe A, and with the annular groove d and recessed ilange C, combined with the shelf D to set into the said groove d, and projection b to work in the recess n, in the manner and for the purpose substantially as described.
